     This class provides a description of an individual file entry in a
     zip archive. It details, amongst other things, the original size
     and compressed size of the file, the version and level information
     of the compression technique, details about extra information
     stored in the header and the file system date stamp of the file at
     the time it was added to the archive.

     The 'unz_file_infoRef' class is not explicitly used but is
     available to return a reference to a C-level  instance rather than
     providing a complete copy of it in R. This is convenient if one
     wants to a) avoid the computation of copying the object, or b)
     wants to mutate the object. The bindings are not here to make
     element-wise modifications but can be easily generated from the
     'RGCCTranslationUnit' package.

     Typically, instances are created in C code when reading the zip
     archive file via the function 'getZipInfo'. It is not necessarily
     useful to create instances manually within R.
